Different Ways to Print Exception Messages in Java

In Java, there are three methods to print exception information. All of them are present in the Throwable class. Since Throwable is the base class for all exceptions and errors, we can use these three methods on any exception object. 

Methods to Print Exceptions in Java

There are three methods to print exception messages in Java. These are:

1. java.lang.Throwable.printStackTrace() method: 

By using this method, we will get the name(e.g., java.lang.ArithmeticException) and description(e.g., / by zero) of an exception separated by a colon, and the stack trace (wherein the code, that exception has occurred) in the next line. 

Syntax: 

public void printStackTrace()

Runtime Exception: 

java.lang.ArithmeticException: / by zero
 at Test.main(Test.java:9)

Output:

java.lang.ArithmeticException: / by zero

2. toString() method: 

Using this method will only get the name and description of an exception. Note that this method is overridden in the Throwable class. 

java.lang.ArithmeticException: / by zero

3. java.lang.Throwable.getMessage() method: 

Using this method, we will only get a description of an exception. 

Syntax: 

public String getMessage()
